Implementation scheme for end-to-end quality of service (QoS) sessions over internet

摘要

With the significant increase in the Internet applications and services which have definite QoS requirements and the resources on the Internet being shared, the need of end-to-end QoS sessions has become critical. The existing QoS mechanisms provide the path selection mechanism in distributed manner which do not necessarily support the end-to-end QoS requirements. We build propose an evolutionary framework which provides support for optimal end-to-end QoS sessions. Implementation of end to end QoS sessions fall under three distinct planes: session control plane, network control plane and data forwarding plane. In this paper we describe the implementation requirements, various choices and the implementation scheme for building end-to-end QoS sessions over Internet.
